A hydraulic machine includes a valve plate, with first and second fluid ports in a surface thereof. A cylinder barrel is rotatably coupled to the valve plate. A plurality of cylinders is formed in the cylinder barrel, such that, as the barrel rotates, each cylinder is coupled to the first and second fluid ports, sequentially. First and second pressure relief ports are formed in the surface of the valve plate between the first and second fluid ports at top- and bottom-dead-center, respectively. A cross-port bore is formed in the valve plate, placing the first and second pressure relief ports in fluid communication with each other. As each cylinder rotates to top-dead-center, an opposite cylinder rotates to bottom-dead-center. The respective cylinders are coupled to the first and second pressure relief ports, such that differential pressure in the cylinders is equalized.
Une machine hydraulique comprend un plateau de distribution qui comporte dans sa surface des premier et deuxième orifices pour le fluide. Un corps à cylindres est couplé rotatif au plateau de distribution. Une pluralité de cylindres est formée dans le corps à cylindres de sorte que, lorsque le corps tourne, chaque cylindre soit couplé de manière séquentielle aux premier et deuxième orifices pour le fluide. Des premier et deuxième orifices de décharge sont formés dans la surface du plateau de distribution entre les premier et deuxième orifices pour le fluide, respectivement au niveau du point mort haut et du point mort bas. Un orifice transversal est formé dans le plateau de distribution et place les premier et deuxième orifices de décharge en communication mutuelle par le fluide. Lorsque chaque cylindre tourne vers le point mort haut, un cylindre opposé tourne vers le point mort bas. Les cylindres respectifs sont couplés aux premier et deuxième orifices de décharge de sorte que la différence de pression dans les cylindres soit équilibrée.
